Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.04140 | $0.04140 |
| Opus 5 | $0.02070 | $0.02070 |
| Sonnet 5 | $0.00828 | $0.00828 |
| Haiku 4.5 | $0.00414 | $0.00414 |
Grade A, and why
project-ContemPlace CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What This Is
ContemPlace is a modern commonplace book that auto-gardens into an MCP-connected PKM system. Capture idea fragments from Telegram or any MCP client — the system structures, embeds, and links them into a searchable knowledge graph in Postgres (pgvector). A nightly gardening pipeline surfaces similarity connections and detects topic clusters.
It is not a notes app. Notes are written by the capture agent, not the user. Users send raw input and receive confirmations. The raw input is always preserved alongside the structured fragment.
Stack
| Layer | Technology |
|---|---|
| Database | Supabase (Postgres 16 + pgvector) |
| Compute | Cloudflare Workers (TypeScript, V8 runtime) |
| Object storage | Cloudflare R2 (photo attachments from Telegram) |
| Capture interface | Telegram bot (webhook-based, not polling) |
| AI gateway | OpenRouter (https://openrouter.ai/api/v1), OpenAI-compatible SDK |
| Embeddings | openai/text-embedding-3-small — 1536 dimensions (default, no truncation). Configurable via EMBED_MODEL env var. |
| Capture LLM | anthropic/claude-haiku-4-5 — configurable via CAPTURE_MODEL env var |
| Dashboard | Cloudflare Pages (vanilla HTML/CSS/ES-modules SPA) + Dashboard API Worker (contemplace-dashboard-api) |
Architecture
Cloudflare Workers handles the Telegram webhook. Supabase is the database only — no Edge Functions.
The capture flow is async: the Worker returns 200 to Telegram immediately, then processes in the background via ctx.waitUntil().
Single capture path: The Telegram Worker delegates capture to the MCP Worker via a Cloudflare Service Binding (in-process RPC, no HTTP hop). The capture pipeline lives in mcp/src/pipeline.ts — one source of truth for all gateways.
On-demand gardening: The MCP Worker triggers the Gardener via a second Service Binding (env.GARDENER_SERVICE.trigger()) — in-process RPC, same pattern as capture. CF Workers on the same zone cannot call each other via HTTP (error 1042), so Service Bindings are the only option for Worker-to-Worker communication.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

project-ContemPlace CLAUDE.md is an instructions file published in the GitHub repository freegyes/project-ContemPlace (3 stars, last pushed 5mo ago), licensed MIT. It adds 4,140 tokens to every session, about $0.0207 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
